Noby, you do realize that the GT3 RS you pictured has a fair amount of negative camber in the rear. That camber will allow a more agressive offset (because the top of the tire will be canted inward at the top of the tire). However, that degree of camber will also result in very bad treadwear on a "street driven" car.

This are my two options I belive, Im a bit afraid which combo will have the best rear look as like that gt3rs exacly on the fender so it lines up nice with the body and the front.

Last opinion guys before I order, give me your thought beside this 60 pages

18 x 9 5-130 ET50
18 x 11 5-130 ET56

18 x 10 5-130 ET50
18 x 9 5-130 50

Noby, you realize the tires and set-up are also part of the equation. What size tires are you going to use on the wheels you list above? How much camber do you intend to run on the rear wheels?

NOBY

Im not sure but I want to run 285 at least maybe 295 if its possible, when it comes to camber Im n00b dont know nothing about that, only that my coilovers that I will install can be camber adjusted.

Run the following:
9 et50 front with 235 or 245/40/18 rubber
10 et50 with 285/40/18 rubber

If you go with the 11" wheel with the 56 offset and it sticks out a tad too far you are going to be pissed! If you sole purpose for going after the 11" is to run 295's there is NO NEED TO! Run the 285 on the 10" wheel. You could probably squeeze a 295/30 in the 10" wheel but why?

Noby, listen to this man, he knows what he;s talking about.
As Dell stressed there is no reason to go with a 285 exception being is if a set of wheels came with something other than that.

Listed below are the wheels you selected and the change (in mm) in clearance in the inside and outside of the wheel. Too little inner clearance and the wheel can rub the struts, push too far out and you'll rub the fender

18 x 9 5-130 ET50 -13mm/+13mm
18 x 11 5-130 ET56 -4mm/+22

18 x 10 5-130 ET50 +15/+15
18 x 9 5-130 ET50 -13mm/+13mm

Dell, is correct that the second group will probably fit the best. However, it represents a 1" increase (in width) at the front and no increase at the rear. That doesn't make a whole lot of sense to me, but you could run a 235/285 tire combo with that that should work pretty well.

The first set is risky on the rears but it may just work (no guarantees just my educated guess) if you run 235/285 combo and a touch more rear camber than factory specs. If it works that may give you the fender filling look you want.

Good luck.

+1 on what Ray and Dell have stated. The second set of wheels listed in Ray's post (#68) above is what I would do. Once you have them mounted, if you wanted them pushed out more (which I doubt that you will) you could add 5mm spacers.

On the other hand, if you get the 11" rear and they stick out too far and the tires rub on the fenders, then you will be stuck with $1,900 of rear wheels that don't fit well.

NOBY

What does not make sense, I dont get this, something wrong with the second set? hmm...

LVDell

NOBY....what do you mean "something wrong with the second set"?

NOBY

Ray S says something about an 1" increase that does not make any sense, what does he mean?

I have emailed in my order on the 50ET versions as LVDELL recommended, everything hands on you m8 =) hah...

Thanks for all help, I will update this thread when they arrive =)

LVDell

The factory wheel is an 8" wheel and you are moving to a 9" wide front wheel which is a 1" increase. Since you are holding the offset constant at 50 you are adding 1/2 of that inch (13mm) to each side of the "factory" size. Doing that means the wheel will sit 13mm closer on the inside and 13mm further out on the outside. Sure, the outside looks great but giving up 13mm on the inside is what you need to be undestanding of. If you go to a wider tire than need be you are asking for rubbing issues. For example, I run the 235/40 on my street wheels with no problem (8.5" wheel) but on my 8.5" and 9" track wheels I run the 245/40 tire which is 10mm wider and also a few tenths of an inch taller so I get rubbing of the tire on the fender liner at full lock.

I think you should be just fine without any rubbing issues up front as long as you stick with the 235/40.

If you need justification to go with the 11 ET56. Read the following.

TireRack recommends an 18x11 ET55
Techart sells and recommends an 18x11 ET51 (even more aggressive)

LInks explicitly talking about 18x11 ET56 and it fitting: http://www.6speedonline.com/forums/s...95&postcount=5

http://www.6speedonline.com/forums/s...d.php?t=115010

I would strongly consider the experience of those that have done it vs. those with opinions about why it won't work

NOBY

Oh god, so maybe 11" will work but no one can proof it?

But is 18x10 ET50 more agressive then 18x11 ET56?
